A climbing vine with intricate flowers and a long ethnobotanical record for nervousness and insomnia. Lead compound: vitexin.
Passionflower (Passiflora incarnata) is a climbing vine belonging to the Passifloraceae family, native to southeastern United States and parts of Central America. This plant can be found in Alabama, Arkansas, Bermuda, Florida, Georgia, Illinois, and Indiana. Known for its medicinal properties, passionflower has been used traditionally for stress and anxiety reduction, with documented benefits including reduced pre-procedural and generalized anxiety. Additionally, it enhances sleep quality by improving overall sleep patterns. One distinctive feature of the plant is the unique, intricate corolla of its flowers, which often appear purple or white. Another notable characteristic is the presence of vitexin, a flavonoid compound found in various parts of the plant including the aerial portions, leaves, and flowers.

Start with passionflower as a simple, low-maintenance plant for beginners.
Passionflower seeds or young plants, potting soil, containers with drainage holes.
Plant in spring after the last frost, or start seeds indoors about 6 weeks before the last expected frost.
Use well-draining potting mix. Ensure containers are at least 12 inches wide and deep.
Direct sow seeds outdoors after danger of frost, or start indoors and transplant young plants once they have several leaves.
Keep soil consistently moist. Place in a sunny spot with at least 6 hours of direct sunlight daily.
Water when the top inch of soil feels dry, and fertilize every 4-6 weeks with a balanced fertilizer.
Prune in late winter to early spring to encourage new growth. Remove dead leaves and spent flowers.
